Abstract
The invention discloses a method for deformation adjustment of cylinder type plastic parts. The method comprises the following specific steps: dimension adjustment, reversible deformation and structural adjustment. By adopting the method, deformation dimensions of the cylinder type plastic parts can be adjusted in advance, one-time dimension adjustment time is saved at least, the mold dimension modification cost is reduced, the service life of a mold is prolonged, and in addition, the adjustment method is simple and easy to operate.
Description
Technical field
The invention belongs to technical field of mold, be specifically related to a kind ofly be applied to the darker cylindrical parts plastic of the degree of depth, the method that can it be regulated well to be out of shape.
Background technology
The application of current plastic applications is more and more extensive, have the darker plastic of a lot of degree of depth to be employed, but this class plastic percent defective is very high, mainly because plastic produces deformation of products more deeply due to the degree of depth, cause product defective with scrap.Existing method is the modified product comparison True Data according to producing, then regulates the size of mould according to deformation of products amount; If but deformation of products is comparatively large, mould may be caused to scrap and reform; If deformation of products is less, then needs to freeze, the mold use life-span can be reduced like this; Due to lacking of regulatory function in advance, the manufacturing expense of mould can be made greatly to increase, and modification time also can increase, the friendship phase of delay product.
Therefore, developing a kind of simple and effective deformation adjustment method for the cylindrical parts plastic that the degree of depth is darker is those skilled in the art institute urgent need to solve the problem.
Summary of the invention
For solving the problem, the invention discloses a kind of method for cylindrical parts plastic deformation adjustment.
In order to achieve the above object, the invention provides following technical scheme:
For a method for cylindrical parts plastic deformation adjustment, concrete steps comprise
(1) size adjusting: do mold flow analysis to cylindrical parts plastic product in advance, knows the deflection of cylindrical parts plastic, according to the size adjusting that deflection carries out in advance to mould;
(2) reversible deformation: the position of distortion is arranged at top and sidewall etc. for cylindrical parts plastic, and mould does corresponding reversible deformation;
(3) structural adjustment: the die in mould is split, and adopt the mode of mold insert to ressemble.
As preferably, in step (2), the concrete grammar of reversible deformation is: for the part of the depressions such as the top of cylindrical parts plastic and sidewall, mould does corresponding projection.
As preferably, in step (3), after splitting the die in mould, the quantity of die is 2-4 block.
The invention provides a kind of method for cylindrical parts plastic deformation adjustment, comprise size adjusting, reversible deformation and structural adjustment simply.Specifically first mold flow analysis is done to cylindrical parts plastic product, i.e. predeformation, know the deflection of cylindrical parts plastic, utilize the data of deformation of products to carry out size adjusting in advance to mould, and for the top of cylindrical parts plastic and sidewall there being the position of distortion, mould does corresponding reversible deformation, namely on top and sidewall, there is the part of depression, corresponding projection is made in relevant position on mould, like this will because of distortion by the shape of the portion concave of product projection to product needed when actual production goes out product, can ensure that product is truly produce can Reducing distortion amount, but the product produced can not be met and required size meets completely, therefore also the most last structural adjustment is needed, concrete grammar is split by the die in mould, and adopt the method for mold insert to ressemble, be convenient to do the size of finely tuning and reaching required by client for the size of product in the future.
The present invention compared with prior art, adjusts the distortion size of cylindrical parts plastic in advance, can be reduced by least the size adjusting time once, also can reduce the cost of die size amendment, extend the mold use life-span, and method of adjustment is simple to operation.
Accompanying drawing explanation
Fig. 1 is the region of step (2) reversible deformation in the embodiment of the present invention;
Fig. 2 is that in the embodiment of the present invention, in step (3), die core insert assembles schematic diagram.
Detailed description of the invention
Below with reference to specific embodiment, technical scheme provided by the invention is described in detail, following detailed description of the invention should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.
Embodiment:
The present invention is a kind of method for cylindrical parts plastic deformation adjustment, and concrete steps comprise
(1) size adjusting: do mold flow analysis to cylindrical parts plastic product in advance, knows the deflection of cylindrical parts plastic, according to the size adjusting that deflection carries out in advance to mould;
(2) reversible deformation: for the part of the depressions such as the top of cylindrical parts plastic and sidewall, mould does corresponding projection;
(3) structural adjustment: 2-4 block is divided into the die in mould, and adopt the mode of mold insert to ressemble.
During concrete enforcement, as shown in Figure 1, at product space 1, reversible deformation has been done at place, the part of mould product depression is done projection on mould, such product actual production out time, will because of distortion by the shape being recessed into product needed of product projection, such can ensure product truly produce can deflection little, but this can not meet production and out meet completely with the size required, this needs the adjustment of Design of Dies structure, as shown in Figure 2, first die 2 and the second die 3 adopt the mode of mold insert to assemble up, the benefit done like this is the fine setting of the product size be convenient in the future, finally reach the size of customer requirement.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
